Introduction Heat from electronic devices is an integral part of information processing, not a nuisance that can someday be eliminated. This is a physical principle that is independent of the device of information processing. However, when viewed in the historical perspective, the severity of heat problems has not monotonically increased. It came to the fore some time ago, … [Read more...]
An Overview of Liquid Coolants for Electronics Cooling
Introduction The cooling of electronic parts has become a major challenge in recent times due to the advancements in the design of faster and smaller components. As a result, different cooling technologies have been developed to efficiently remove the heat from these components [1, 2]. The use of a liquid coolant has become attractive due to the higher heat transfer coefficient … [Read more...]
Micropumping Technologies for Electronics Cooling
Introduction Traditional cooling approaches, consisting typically of external air-cooled heat sinks, are increasingly falling short in meeting the thermal management challenges of emerging electronic systems. Integrated cooling designs are being investigated to eliminate some of the interface contact resistances introduced by add-on heat sinking and to minimize package … [Read more...]
On-Chip Electrowetting Cooling
Introduction Control of component temperatures and temperature gradients is essential for the successful operation and reliability of electronics products [1]. However, conventional cooling methods, such as natural convection or fan-induced air-cooling, cannot cope with the increasing demand for electronics cooling. Therefore, more sophisticated cooling techniques are required. … [Read more...]
